18 :/ I've had older guys hit on me.. and check me out, since I'm homeschooled and go out a LOT during the day.. x)
I'm only 15 );
I got mistaken for being ancient when I was getting a haircut once. I have severely premature greying hair... and I asked the cutter "how old do I look?" And she goes "Aww honey.... I'm only 40 and you don't look much older than me." And I responded "I'm 23..." because I was at the time LOL.
YOU SHALL NOT PASS!
No way I would mistake you for 25. :c I think you look your age! I'm not really mistaken for being older. Uhh...most people think I'm like...15 when they first meet me. And I'm 17 right now, going on 18 June 5th. xD
Someone thought I was 20, I'm 19 so thats ok.
Most people think I'm about 14 though :(
I am 19 mostly I get people thinking I am between 14 and 16 but every once and a while people will think I am like 22 or 23.
...I think you look about eighteen...but DEFINITELY not in your twenties.
The oldest anyone has ever though I was has been 16 (I'm 18).
I usually don't have people guess my age that much. But I have a friend who's tiny and adorable, and you'd NEVER guess that he just turned 18. He's so childish. It's like he's 15. But then you hear about the things he's DONE, and you're totally shocked.

Some guy tried to get in my pants when I was 16 because he thought I was 19. He failed, if you're curious. Although i'm sure you're not. His sister nearly succeeded, though. She was fiiiiiine.
The oldest for me is 20 but I'm 17, I didn't take it as an insult.
i was never mistaken for someone older ;-; people always deduct a few years from me
i remember once, this lady at the store asked me which grade i was in i made a o.0 look and said i was in college she then said 'what the.. you cant be 18!' so i said 'i'm not, i'm 21 -_-'
that depends :/ without makeup and my usual style of clothes they'll think I'm 16 (I'm 20 :() with it they usually guess my age correctly. I guess I don't look very mature.
THEY CAN'T BREAK YOU IF YOU DON'T HAVE A SPINE
Lol when I was 13 these guys thought I was a uni student.
[tot=joanne]
I always get mistaken the other way. Alot of my friends do too.
I have one friend who is 22 now, but earlier this year, a couple went up to her and asked her where her parents were and why they left her by herself for so long in a coffee shop. She just went "uh...I'm 21."
I'm 16 and when I go out, most people think I'm 21-22. Some guys even asked my to buy them some vodka (legal age to buy vodka here is 18). I went... @
never older...always younger..
i'm 22 and just today someone told me i look 19....maybe i need a new look :)
I apparently look younger, because people say I look like I'm a freshman :c
someone assumed i was 25 when i was 15 lol i look old, apparently
and i really don't think you should be insulted simply because someone thought you were older that's usually a good thing looking older than your actual age is not bad until you pass 30
I once got asked what college I attended.
I was fourteen at the time.
That is all. XD
People have thought I look like a junior before. I'm a freshman.
But they've also thought I'm my mother, and that's rather annoying. XD
